A. Hall & Company built Asia at Aberdeen in 1818, and she first appeared in Lloyd's Register in 1820 with the trade route listed as London to Bombay. The timing was significant: in 1813, the British East India Company had lost its monopoly on trade between India and Britain, opening the route to any ship carrying a license. Asia entered this newly competitive market, sailing to Bombay under Captain Morrice in 1819 and returning to Gravesend by June 1820. She would maintain connections to the India trade throughout her career, often continuing to Calcutta or Bombay after dropping convicts in Sydney. Commerce and punishment traveled the same sea lanes, and ships like Asia served both purposes without contradiction.

Asia's eight convict voyages followed a pattern familiar to the transportation fleet: load human cargo at an English or Irish port, endure three to five months at sea, deliver the convicts to Sydney or Hobart, then pick up whatever return cargo -- whale oil, wool, or nothing -- the colonies could offer. Captain Jason Morice commanded the first voyage in 1820, embarking 190 male convicts at Sheerness; one died en route. By the third voyage, Captain Thomas Stead had taken command, and he would hold the position through the remaining six convict runs. The numbers varied: 100 male convicts on the fourth voyage, 200 female convicts on the fifth, 290 male convicts on the eighth and final run to Hobart in 1835-36. Across all eight voyages, twelve convicts died at sea -- a mortality rate that was low by the standards of the era, though the statistic says nothing about the conditions endured by those who survived.

Asia was not merely a convict ship. Between her fourth and fifth convict voyages, she made a single run for the East India Company in 1826-27, sailing from the Downs to Whampoa anchorage in China, then on to St. Helena and Quebec before returning to the Thames. The voyage illustrated the global reach of British maritime commerce: a single ship could serve the convict trade to Australia, the tea trade with China, and the lumber trade with Canada in successive seasons. On her return from the fourth convict voyage in 1828, Asia carried 160 tons of whale oil gathered in the colonies -- a reminder that these ships were economic instruments first, and that every mile of empty hold space was revenue lost.

Asia's final convict voyage delivered 290 men to Hobart in February 1836. Three years later, she made one more run to Australia, this time carrying 267 government-assisted emigrants from Plymouth to Sydney -- free people, traveling willingly, though likely in conditions not dramatically better than steerage on a convict ship. Lloyd's Register for 1839 showed her with a new master named Govey, having undergone a large repair in 1835 and small repairs in 1838. She was last listed in the register in 1845 with D. Smith as master. After that, the record goes silent. No dramatic sinking, no heroic final voyage -- just the quiet disappearance of a working ship that had outlived her usefulness. By the time her name was dropped from the register, Asia had been afloat for twenty-seven years, long enough to have carried people who were born in a world without railways to a continent that was still being mapped.
